摘要：

An experimental technique is described for the accurate measurement of both the composition and molar volume of individual phases in fluid-phase equilibria involving several coexisting phases. The technique enables the equilibrium compositions and molar volumes to be determined from visual measurements of phase volumes only; no sampling is required. Results are presented for liquid-liquid-gas equilibrium for trans-decalin-CO//2 mixtures and 2-propanol-water-CO//2 mixtures and liquid-liquid-liquid-gas equilibrium for 2-propanol-water-CO//2 mixtures. This work is relevant to extraction.
